I'm using SteamOS 3.7.8 (Xorg session) as the host and a distrobox-like container (https://github.com/alexsch01/distbox) that's running Fedora 42 / KDE Plasma 6.3.5 STEPS TO REPRODUCE 1. $ sudo dnf install plasma-desktop 2. $ startplasma-wayland 3. Use KDE Plasma feature in SteamOS to make spawned X11 window fullscreen mode 4. Once it's fullscreen mode, use the keyboard to see it works in the nested desktop properly 5. Press META+V to launch the clipboard history from host SteamOS's version of Plasma OBSERVED RESULT - All keys do not function properly SOFTWARE/OS VERSIONS Fedora 42 KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0
